Wasn't the engine due to tougher emissions regulations? I thought that it was supposed to have something better, but ended up stuck with what it got because the original plans wouldn't have passed emissions by the time they actually started producing the car.

As for being polite, if the buyers have the disposable cash for it, who am I to judge what they buy? Most cars are luxury purchases to an extent. Almost nobody buys the minimum necessary. It's just a matter of how much unnecessary spending you do.
